The main reason I see is, that I have not Network-Address available. It is a standalone-computer. Q: Does the profiling work anyhow, when the computer has no network-address available? Is this some kind of prerequisite? [Nagarajan, Guru] This is possible. Thinking about it the Agent Controller connection is on the basis on the "Host Name" or the "Network address". 2) When profiling my app, I can run eg. Memory-analysis. When switiching the type to Execution-analysis, no data are displayed on my view. Restart Eclipse, then profiling works. Is there a known problem, that the data-collection from one type cannot be switched to another type? Note: The problem only appears with Execution-analysis. [Nagarajan, Guru] This is a known issue and is to be resolved as soon as possible. 3) My app starts a DB-connection and then retrieves the information via DB-statements. Since my app starts therefore a Server, the creation of a Server-socket might take some time in my code. This time I can hardly influence, especially since I am using another Bean. Problem I am faced with is, that the data-collection slows down my computer and it takes some time for the start-up of my app. Due to this time-consumption, the Socket cannot be opened and it run into a timeout. [Nagarajan, Guru] Can you check your filters to see what classes you are interested in collecting the information about. If the filter set does not include the java.net.* package classes. The profiler instruments the classes specified by the filter and has an impact on your application start time. Please see the http://www.eclipse.org/tptp/platform/documents/tutorials/jvmti/Java_Appl ication_Profiling_using_TPTP-r4-3.html for information on editing your filters. Let me know if this makes a difference. Q: Is it possible to start profiling just after a specific line? Resp. profile only between two specific line codes? (Similar like Debugging) [Nagarajan, Guru] We do not currently support this feature. This is also referred to as the "Code fragment" profiling. There is an enhancement request for this. 4) Collecting data with time-execution and time-profile, execution flow, I get some nice graph and some nice time-lines. Is there a way to detect which time-line belongs to which method/class? Cause this information is quite bulky. :) [Nagarajan, Guru] Yes you can - you can pick a method in the Interaction diagrams and go to the selected method.
